Y = 2/5x + 3. The slope here is 2/5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal. we " flip " the slope and change the sign. So the perpendicular line will need a slope of -5/2.
y = mx + b
slope(m) = -5/2
(4,-4)....x = 4 and y = -4
now we sub and find b, the y int
-4 = -5/2(4) + b
-4 = - 10 + b
-4 + 10 = b
6 = b
so ur perpendicular line is : y = -5/2x + 6
ThTa would be worked out by proportion
114% = £940.50
100% = (940.50 * 100 ) / 114

1.) -4
2.) Parenthesis, so probably 1+1
I could be wrong. Sorry XD
Answer:
Huh? is it triangle? and right triangle? if it is its 62^2 = 12^2 + x^2
Step-by-step explanation:
I will not do it all. I will set it up for you.
Area = length times width
A = LW
(9x^2 + 6x - 3) = L(3x - 1)
To find L, divide both sides by (3x - 1) using long division.
After finding L, go back to A = LW but this time use the NEW AREA given to be (9x^2+ 12x+ 3).
Set Up:
(9x^2+ 12x+ 3) = LW
Note: Plug the L you found above into (9x^2+ 12x+ 3) = LW and then solve for W.
Take it from here.
